One of the biggest challenges faced by traffic management centre operators is how to optimise traffic flow for factors beyond vehicle flow. Operators often work with little more than general traffic speed, volume and occupancy data, so they typically aren’t equipped to know how a traffic management strategy can influence air quality, how a diversion in response to an incident might impact public transport operations, or whether adjusting signal timings for one intersection could lead to a worse situation for the overall network. Combining the Yunex Traffic traffic management system Concert with the simulation capabilities of Aimsun and air quality calculations from IMMIS enables a more holistic approach to mobility management.
